ABSTRACT:
In a chip type common mode choke coil, a plurality of non-magnetic sheets on which conductor lines are formed are laminated one on another to form a non-magnetic member, and the conductor lines are connected to form primary and secondary coils inside the non-magnetic member, and a pair of magnetic layers are formed on the upper and lower surface of the non-magnetic member, and magnetic cores are arranged substantially at the centers of the loops of the coils in such a manner that they penetrate the non-magnetic member and are connected to the pair of magnetic layers, whereby a closed magnetic path crossing the primary and secondary coils is formed.
